Looking awesome Andy. Back in 2011 when I was doing the Link ECU install I got the O2 sensor locations wrong by putting them on the downstream side of leaky collector joins that were impossible to fully seal up, and had to move them and muck up my new header coatings - I recall you have V-bands...

Hi all, small update, now with about 2500kms on it. Have become obsessed with fine tuning - can't get it totally perfect at 1-2% throttle because very small changes have a major impact on airflow which cause pretty large dynamic changes in AFR, but it's pretty good overall. On the open road...

Hi all, hope you had a great Christmas break. The Wolseley 6/90 revival project is finished (well 99% - they are never fully finished are they?!) Hamish did a great job completing the subtle but effective new front wheel arches, and I repainted the front guards. Andy Smith at Smith Auto in...

Good info. That's a shame - I bought an EFI unit off Andy when he was back at Hilborn in 2010 and it runs good from idle to wide open on the 440 SBC in my McLaren. Andrew

Hi all, Hamish has finished one of the hand-formed new front wheel arches and has it tacked in. It has taken him ages but it is extremely good and I thinking I'll basically be able to just prime and paint the finished article. He has learned a lot from the first one so the set-up and forming...

On the subject of filters, I was looking through a datalog the other day from recent fang on the motorway. I don't usually pay much attention to MAP readings because I use Alpha-N fueling but I do have a MAP sensor logged. When wide open starting at about 3k my MAP reading dropped steadily...

Very useful sounding feature indeed

Hi Ox, I love your fabricated IR solutions! I run speed density on the Hilborn 440SBC in the canam car and it is super docile and well mannered so i agree with you there. The issue it has got though is that the MAP resolution is poor due to the IR so in the lower to mid RPM range it will...

Hi all, I have put a lot of effort into setting up and fine tuning a Speedmaster budget 8 stack for the street on a cammed LS3. It runs pretty good. There are a few things relevant to this discussion. - IR intakes do not produce a MAP signal that is properly representative of engine load...

Hi JP, yes I have two resonators about a metre back from the header collectors - possibly too early in the system but the only place I had room - and even with the resonators in place the flowmasters are over the top. I made a mistake above - I actually fitted a pair of Dynomax Super Turbo...

Hi All, Still making incremental progress, but still waiting for final front guard lip mods to be completed for certification. Have the car pretty much 95% tuned and running well. The 8-stack is incredibly fussy to tune at very low throttle angles where small changes create large percentage...

Hi Doug, I run an inverted 930 Porsche 4 speed trans-axle and had major issues initially with it puking oil out the breather and overflowing the small Moroso catch can I use. I converted my side filler plug to a -8AN female nipple and have my can continuously draining back into the trans. It...

No - load function starts TPS then transitions to MAP. Holley's use case is a big cammed v8 with erratic and low manifold vacuum at idle and low rpm low load where TPS is preferable as an indicator of load, transitioning to MAP at the point there is a usable signal with decent resolution, say...

Hi Stephen, don't get me wrong on the Holley - it will work fine if you commit the time. The main benefits of it is the huge forum support and the user friendly software. The main issues I have with it are the hybrid Alpha N mode (Alpha N for idle and light cruise, transitioning to Speed...

Hi Stephen, I'm running a Holley HP on a LS3 8-stack set-up on my restomod project. Personally I would use a crank trigger for timing because of its much superior stability and just use the distributor for cam sync assuming you want to run sequential. I'm using full Alpha N due to the...

Hi Andy, My main hoop was integral and powder-coated satin black as part of the whole chassis. I had all my suspension arms and radius rods HPC coated and they came up well, durable and and settles down to a semi-gloss silver/grey over time. What's the MANZ drama about your roll protection...

Agree with the recommendation to go hyd roller. I ate two XE flat tappet cams in a row before switching. Don't sweat the cam specs too much - just decide what you want from the engine. If we take the comp cams 281HR, 284HR, and 290HR grinds as a reasonable spread for a street performance...

Getting closer Andy - looking superb! Cheers, Andrew

Hi Coleman, I've got a Shafiroff 434 in my McLaren canam replica. This is a similar configuration to the 427 you linked to. It is very torquey and flexible, and about as much as the chassis and me as driver can handle. Apart from the fact that its enough already and I'd struggle to find a...
